FunctionOrphan nuclear receptor of retinal photoreceptor cells. Transcriptional factor that is an activator of rod development and repressor of cone development. Binds the promoter region of a number of rod- and cone-specific genes, including rhodopsin, M-and S-opsin and rod-specific phosphodiesterase beta subunit. Enhances rhodopsin expression. Represses M- and S-cone opsin expression.
Tissue specificityEye specific; found solely in the outer nuclear layer of the adult neurosensory retina, where the nuclei of cone and rod photoreceptors reside.
Involvement in diseaseDefects in NR2E3 are a cause of enhanced S cone syndrome (ESCS) [MIM:268100]. ESCS is an autosomal recessive retinopathy in which patients have increased sensitivity to blue light; perception of blue light is mediated by what is normally the least populous cone photoreceptor subtype, the S (short wavelength, blue) cones. ESCS is also associated with visual loss, with night blindness occurring from early in life, varying degrees of L (long, red)- and M (middle, green)-cone vision, and retinal degeneration. Defects in NR2E3 are the cause of retinitis pigmentosa type 37 (RP37) [MIM:611131]. RP leads to degeneration of retinal photoreceptor cells. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. RP37 inheritance is autosomal dominant.
Sequence similaritiesBelongs to the nuclear hormone receptor family. NR2 subfamily. Contains 1 nuclear receptor DNA-binding domain.
Post-translational modificationsDi- and tri-sumoylated in developing retina. PIAS3-mediated sumoylation promotes repression of cone-specific gene expression and activation of rod-specific genes. Sumoylation on Lys-185 appears to be the main site.
